Invitrogen coated ELISA kits are ready-to-use, and have been tested to provide very low inter- and intra-assay variability, with very high lot-to-lot consistency. ELISA kits with coated plates help ensure that you obtain consistent ELISA performance and are designed for labs that require validated and comprehensively tested kits.

Benefits of coated ELISA kits:

• Validated performance⁠—tested for plate variability (CV) and final kit validation testing before shipping out
• Easy-to-use⁠—includes all the required assay buffers and reagents, and a straightforward protocol
• Fast⁠—pre-coated plates allow for a workflow typically completed within four hours

Invitrogen Instant ELISA Kits have a condensed workflow format designed to alleviate the inconveniences of multiple preparation and incubation steps. In conventional ELISA kits, the precoated plates provide only the capture antibody, to which the sample and detection reagents must be added sequentially. In contrast, Instant ELISA Kits come with ready-to-use plates that contain all necessary assay components—including capture antibody and lyophilized detection antibody, streptavidin-HRP, and sample diluent. These prepared plates greatly reduce pipetting time and enable a simple one-wash protocol. Furthermore, serially diluted, lyophilized protein standards are provided in additional strip wells, eliminating the need for plate setup and serial dilutions to create a standard curve, leaving less room for error.

Benefits of Instant ELISA kits

• Ready-to-use—microplates contain all necessary assay components
• Time saving—standards are already serially diluted in the plate
• Convenient—sequential addition of reagents during assay minimized

Figure 1. Comparison of Instant ELISA technology vs. conventional ELISA procedures. With Instant ELISA kits, all the preparation work has been done for you, helping decrease hands-on time per experiment. In addition, Instant ELISA kits come with a full 96-well plate for your samples and two separately packed standards. This enables the use of all 96 wells for your samples expanding your ELISA capacity by 20%.

Table 1. Comparing conventional ELISA and Instant ELISA workflow steps. Fewer steps help save time and reduce variation. There are only 7 working steps when using an Instant ELISA kit, as opposed to 17 steps when performing a conventional ELISA. Therefore, you can decrease total hands-on time per experiment to about 1 hour by adopting the Instant ELISA technique.

ELISAs can be used to identify and quantitate just about any type of analyte. When designing an ELISA for your unique target of interest, deciding which components are right for you is often the most difficult part. The ELISA Builder is an online selection tool that guides you through a short series of questions about your specific ELISA and then recommends all the components you’ll need—from plates to stop solution.

Invitrogen uncoated kits are ideal for experienced ELISA users on a budget with less stringent requirements for inter- and intra- assay variance. These kits have the reagents needed to coat-your-own plates using an overnight process and run the assay. Kit configurations can provide easy-to-use, flexible options.

Benefits of uncoated ELISA kits

• Pre-titrated and optimized—matched antibody pairs and all provided reagents optimized for ELISA development
• Many options for kit configuration—purchase based on the volume of your assay through a choice of package sizes, including 2-, 10-, and 20-plate kits
• Complete—includes all the essential reagents and buffers to limit variability. Generic reagents like wash and stop solution not included
• Affordable—priced to accommodate demanding budgets and help maximize your research

Invitrogen antibody pair kits contain pre-matched antibody pairs, standards, and streptavidin-HRP to develop your own ELISA assays. PeproTech Development kits are also used to design new ELISA protocols, with a variety of targets available in both ABTS and TMB formats for flexibility.

Benefits of matched antibody pair kits

• Flexible—matched antibody pairs can be used for ELISA or with other immunoassay platforms
• Convenient packaging option—All-in-one buffer kit sold separately, if needed for ELISA development
